The Key Dunes are located in northern Poland and are part of the Slowinski National Park.
Due to the action of wind and the accumulation of sand from the coast, the Slowinski Dune gradually grew to a size that reaches 30 meters at its highest point. The Slowinski Dune's shape changes with the seasons, earning it the nickname "the moving dune."
Poland's climate lies somewhere between the continental climate of Eastern Europe and the maritime climate of Western Europe. The country's climate is primarily temperate, with broadleaf forests transitioning from maritime to continental. Generally, Poland enjoys a mild climate year-round, with neither severe winters nor extreme summers.
Regionally, western and northern Poland have a predominantly maritime climate, characterized by mild, wet winters and cool, rainy summers.
In Poland, the first green leaves of spring, that is, the first buds and leaf sprouts, usually appear in early April. May to September each year is the most beautiful season in Poland, with warm and sunny weather. September is known as the beginning of "Polish Golden Autumn". By October and November, the leaves turn yellow, gold, and red, and then fall. In Poland, there are an average of 300 days of cloudy weather a year. Therefore, if broken down by weather conditions (such as temperature), Poland has six seasons. In addition to the four typical European seasons of spring, summer, autumn and winter, there are two other seasons: "early spring" and "early winter."
